[Bug 1137817] Re: [ivb] [WORTMANN TERRA MOBILE ULTRABOOK 1450 II] System freeze after high memory usage
1) yes
2) yes
3) kernelBisection sounds really hard to me. I have git experience but no experience in building kernel versions from sources :-/
Did you expect that if I install the 3.12.9 I should see the same
behavior as in 3.13.0 ? So is it helpful if I try 3.12.9 or is it
necessary to compile a specific kernel version from the sources now?

Title:
[ivb] [WORTMANN TERRA MOBILE ULTRABOOK 1450 II] System freeze after
high memory usage
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I have a Wortmann Terra Mobile 1450 II:
http://www.wortmann.de/de-de/product/aa_terra_mobile_nb/1220285/terra-mobile-ultrabook-1450-ii.aspx
that randomly system freezes on Ubuntu 12.10 64 bit since I installed
my system in Dec. 2012. When the system freezes no mouse , no
keyboard, no REISUB is possible. The screen is corrupted and did not
update. The only key board functionality which is still possible is
Fn+F9 (switch display on/off). I need to switch off the system hard.
The freeze occurs when the system runs on battery as also when it is plugged. When the system freeze occurs with power adapter plugged the system switches off when I disconnect the power adapter - even if the battery is full charged.
But the powermanagement in general seems to work perfect in Ubuntu 12.10.
To me it looks like the system freeze occurs often after high memory usage.
I can use the system with a few applications (Thunderbird / Firefox) for long time (several hours) without any freeze.
But when I start java programming the probability increases that the problem occurs. This means:
I start Eclipse 4.2, MySQL and GlassFish 3.2 Server. I open a lot of browser windows and read and write much files to disk.
The memory usage in this case increases from less then 1GB to more than 3GB (on total 8GB Ram) - I do not know if this is relevant - but maybe.
I observe the situation for more than two months. As I use my system for work I have freezes one or two times a day - mostly when I have much work ;-) I develop JEE server business applications - so in the situation when the system freezes there is really no heavy graphic load. I am using Gnome Shell.
The freeze seems to be absolutely randomly - I can not reproduce the system freeze.
I can not be sure but it seems to me that since yesterday the system shuts down after some seconds when it feezes. I notice this because I tried to login via ssh to collect the data of the file /sys/kernel/debug/dri/0/i915_error_state. But as the system shuts down I was not able to check the content.
